Both of you need to go and do some research, look at various turbocharged UZs for example the Hyperdrive one, the GTEIGHT Celica, the Hillbilly GTS Holden - all of them report getting usable boost pretty much from idle, certainly below 2000rpm - i quote "it makes boost from about 1500rpm, has 16 psi by 4300"
You simply cannot do that with a 1JZ and still make big power, that is the point i am making.
Furthermore, because it is still an n/a engine, even when it is "off-boost" it is still driving as it would from the factory, not a doughy low-compression engine with no boost.
